Ayone know the wattage used at a Rock concert?


I just attended a Dave Matthews concert last night at a large outdoor venue (very good show). The sound level was incredible, the bass was chest thumping. I'm wondering what type of amplification is used at something like this, ie, number of amps, type of amps, number of watts, that type of thing. Anyone have any experience with this stuff? I kinda like trivial knowlegde of this sort. Thanks.

Just a bit of trivia, The Rolling Stones P.A. system had an incredible 50 Watts for their first concert in New York City. Talk about changing times!

But then again, isn't the benefit of a huge amount of power one of either powering inefficient speakers or handling dynamic peaks easily?
I think David Gilmore of Pink was using 1000 watts for his geetar a few years back at the big out door shows.

Happy Listening!!
This will provide some interesting reading...it is about the Grateful Dead's "Wall of Sound" setup...pretty cool.
